Regulator
Propane regulators must always be installed with the vent facing
downward. Regulators that are not in compartments have been equipped
with a protective cover. Should vent be covered, the regulator cannot
operate.
The regulator has the only moving components in the propane system.
Its sole function is to reduce the high and varied pressure from the
propane containers to safe and consistent low operating pressure. The
small inlet is the first stage, which reduces the container pressure to 10-
13 pounds.
The second stage then reduces the 10-13 pound pressure to an operating
pressure of 11 inches WC (water column) or 6.35 ounces of outlet
pressure to your appliances. The second stage is adjustable and may
need to be adjusted for precise operation. It is suggested this be normal
maintenance and performed once per year. Do not make this adjustment
without a manometer or U-tube. This instrument is required to read actual
pressure.
If pressure is too high, it affects performance and safety. Should pressure
be too low, appliances will not operate correctly. An authorized technician
with proper equipment should perform such tests and adjustments, as
may be required.
The standard type is the “automatic” two stage regulator used on larger
coaches. With both cylinders full of propane, turn the lever on the
regulator towards the cylinder you wish to use first. This will now be the
“supply” cylinder and the other “reserve”. Slowly open both cylinder
valves.
The indicator on top of the regulator will turn bright green or red. When
the cylinder becomes empty the indicator will change to bright orange or
red. Now turn the lever to the side of the full bottle and the green signal
will return. You may now remove the empty bottle to have it refilled
without interrupting the flow from the full bottle. After filling the cylinder,
connect the pigtail hose and slowly open the bottle valve. Do not forget
to check for leakage each time you refill cylinder or disconnect any part
THIS GAS PIPING SYSTEM IS DESIGNED FOR USE WITH
PROPANE ONLY. DO NOT CONNECT NATURAL GAS TO
THIS SYSTEM.
Securely cap inlet when not connected for use. After turning
on gas, except after normal cylinder replacement, test gas
piping and connections to appliances for leakage with soapy
water or bubble solution. Do not use soap products that
contain ammonia or chlorine.
